Getting very suspciious of goings on with GIB

I often play on a table with 3 robots (IMPs). Sometimes I have noticed a fairly consistent pattern where in identical (uncontested or with defensive bids) auctions certain users seem to be consistent beneficiaries of underbids by GIB and other users seem to constistently get the maxiumum bid (eg games vs slams). Without naming names and suggesting anything untoward specifically is there any variable in the siumulations that could cause this to happen. Would they have different bots or does it take account of any aspects of certain users (their playing history) etc. I understand there is the chance of it all being error from simulations but when it happens consistently you start to wonder and log off very quickly

Could be all confirmation bias and coincidence but I do keep seeing the same names

Humans are very good at pattern recognition, to the point where they see patterns where none are present...
